@10newsau: Two German slackliners have just set a new world record, walking between two flying hot air balloon 2,500 metres in the sky on Saturday. The previous record, set in Brazil three years ago, was beaten by a whopping 600 metres, as confirmed by the International Slackline Association. Slacklining is similar to walking a tightrope, but instead of a taut and rigid surface, a slackline is loose and flexible. #10NewsFirst #germany #worldrecord
